Tonight when my car was over speed bumps (in parking lot at quite low speed), I heard some strange noise that seem to come from front wheels (or from where my left foot is). It sounded a bit like metal hitting each other though a bit muffled. I've heard alot of worn rear shock mount complains for M3s. Could this be a worn front shock mount??

(Never heard of the noise from worn shock mounts, so I could only guess.)
